I totally get that — I ran into the same problem when I just needed to fax one form. A lot of apps try to push you into monthly payments, but there are better options. I found a detailed article on
https://derekdubois.net/ explaining which Android fax apps let you pay per fax or even send a few pages for free. The guide compares several services and includes tips on how to scan documents clearly using your phone’s camera. I followed their advice and used one of the pay-per-use apps. It was fast, secure, and I didn’t have to deal with recurring charges. The document arrived perfectly, and I got confirmation within minutes. It’s a great solution for people who only fax occasionally.
